Hi all, I also encountered this problem when I updated my XCode from 14.2 -> 14.3, official release. What worked for me was a sequence of steps: from your project folder, flutter clean ios, then flutter pub get. in terminal, 'cd ios' , and run: pod deintegrate delete podfile.lock in podfile, set platform :ios, '13.0' keep the last block THE SAME as you found it (which is different from steps suggested by johnson0513 above. In my case, it was: post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) end end in ios folder, run: pod install open 'Runner.xcworkspace' => Pods => highlight all packages in 'Targets' => set 'iOS Deployment Target' to 'iOS 11.0' This seems like the manual version of what Johnson0513 suggests, but this manual process was what made all the difference for me. Run the build! You can also build your project on your IDEs like VSCode.
